Insights

Securities Analyst

TL;DR: Officer sold 3,000 WBS shares in two transactions, a routine insider sale with limited apparent impact.

The Form 4 discloses two small open-market dispositions totaling 3,000 shares at roughly $61.60 each, reducing direct ownership to 14,894 shares. These transactions are reported under Section 16 and appear as routine sales rather than option exercises or transfers. For a bank-sized issuer, the share count and amounts disclosed are modest and do not on their face signal a material change to control or corporate strategy.

Corporate Governance Expert

TL;DR: Reported sales are standard insider disposals; disclosure is timely and properly executed by attorney-in-fact.

The filing identifies the reporting person as an executive officer and shows the signature executed by an attorney-in-fact on 09/15/2025. The transactions are coded as sales and include prices and post-transaction holdings, meeting disclosure requirements. No additional derivative activity or linked plan is disclosed on this Form 4.
